Silicon nitride ceramic products
Silicon nitride ceramic material is a special ceramic material with excellent comprehensive performance; SDTC Ceramic Research Institute has more than 40 years of research and development experience in silicon nitride ceramic material, and has undertaken more than 30 countries from National key research projects, high-tech projects and military industry research projects from the "12th Five-Year Plan" period, obtained 17 research results above the ministerial level, obtained 6 patents, and established "800,000 tablets" in the mid-1990s "Si3N4 Ceramic Bearing Ball" and special-shaped product production lines form a research and development platform for Si3N4 ceramic products that integrates scientific research and production; it has a complete set of production technology equipment from raw material processing, molding, firing and processing.
Main application areas:
1) Machinery industry: Silicon nitride ceramic shaft balls can be widely used in electric spindles of high-speed machine tools, bearings of wind turbines, and high temperature and corrosion resistance fields;
2) Metallurgical industry: due to the non-wetting characteristics of silicon nitride ceramics and aluminum liquid, silicon nitride ceramic parts are widely used in aluminum smelting and casting, such as protection tubes, riser tubes, hooks, etc .; silicon nitride ceramic resistance The water ring can be applied to non-destructive flaw detection units for seamless steel tubes; silicon nitride metallurgical rolls can be used for steel production, etc .;
3) Petroleum industry; can be used for petroleum exploration, etc .;
4) The field of high temperature wear resistance and corrosion resistance; silicon nitride ceramic positioning blocks can be used in the production of titanium sponge; silicon nitride ceramic inserts are used in the high temperature reflux area of supercritical industrial boiler swirl burners, etc .;
5) In the field of wave-transmitting materials; due to its excellent wave-transmitting properties, silicon nitride ceramic plates can be applied to the roof of microwave ovens, the detection windows of level gauges, etc .;
6) Auto parts: such as rocker inserts, turbine rotors, cam tappets, etc.
Silicon nitride ceramic turbines-mainly used in turbochargers of high-end automobile engines.
Silicon nitride ceramic bearing ball-widely used in machine tools, wind power generation, petroleum, chemical industry and other industries
Silicon nitride ceramic water blocking ring-the main purpose is to be used on the large-scale seamless steel pipe on-line nondestructive flaw detection machine, replacing the imported products in Japan, and the life span is 2-3 times that of similar products in Japan.
Alumina ceramic burning plate
